MPD now playing integration?

[hrwtech]

I don't have much to offer by way of how but could you offer some some assistance

[Jean-Tinland]

Hi, I'll look into it soon and see if I can integrate something similar to the Spotify or Music/iTunes widget or link the more basic Browser Track widget!

[kvndrsslr]

Here is how I did that:

• install ncmpcpp via brew
• new simple-bar widget with command ncmpcpp --current-song="%a - %t" 2>/dev/null

Could be improved by offering to customize the current-song format in simple-bar settings.

[Jean-Tinland]

As suggested in #176 this could be handled in a future extensible custom widget system! I'll keep you posted here.

Thank you @kvndrsslr for your research.

That (#176) is a great idea indeed!

In case @hrwtech wants to use my approach in the meantime. In the end I opted for mpc (installable through brew install mpc) instead of ncmpcpp for obtaining track info because it also allows to toggle play/pause among other stuff and ncmpcpp is more of a ncurses client than a command line swiss knife. Instead of creating a new widget I just hacked the music/iTunes widget as I do not use Apple Music and if you're using MPD the chance is you do neither. Here are the two files you need to replace:

lib/components/Music.jsx

import { React, run } from 'uebersicht'
import Specter from './Specter.jsx'
import { PlayingIcon, PausedIcon } from './Icons.jsx'

import { refreshData, clickEffect, classnames } from '../utils'

import { getSettings } from '../settings.js'

const { useRef } = React

const Music = ({ output }) => {
  const ref = useRef()
  const settings = getSettings()
  const { widgets, musicWidgetOptions } = settings
  const { musicWidget } = widgets
  if (!musicWidget || !output) return null
  const { playerState, trackInfo } = output
  const { showSpecter } = musicWidgetOptions
  if (trackInfo === '') return null

  const isPlaying = playerState === 'playing'
  const Icon = isPlaying ? PlayingIcon : PausedIcon

  const onClick = (e) => {
    clickEffect(e)
    run(`mpc toggle`).then(refreshData)
  }
  const onMouseEnter = () => {
    const target = ref.current
    if (!target) return
    const inner = target.querySelector('.music__inner')
    const slider = target.querySelector('.music__slider')
    const delta = inner.clientWidth - slider.clientWidth
    if (delta > 0) return
    const timing = Math.round((Math.abs(delta) * 100) / 4)
    Object.assign(slider.style, {
      transform: `translateX(${delta}px)`,
      transition: `transform ${timing}ms linear`
    })
  }
  const onMouseLeave = () => {
    const target = ref.current
    target && target.querySelector('.music__slider').removeAttribute('style')
  }

  const classes = classnames('music', {
    'music--playing': isPlaying
  })

  return (
    <div ref={ref} className={classes} onClick={onClick} onMouseEnter={onMouseEnter} onMouseLeave={onMouseLeave}>
      <Icon className="music__icon" />
      {showSpecter && isPlaying && <Specter />}
      <div className="music__inner">
        <div className="music__slider">
          {trackInfo}
        </div>
      </div>
    </div>
  )
}

In case you are running your mpd server on another host, just search/replace "mpc" with "mpc --host YOUR_HOSTNAME_OR_IP".

Thanks to everyone for their feedback! Unfortunately, this does not work whatsoever.

1. This modification is not built on the most up to date version of Simple-bar
2. There is no "lib/components/Music.jsx" should I assume that you mean "lib/components/data/music.jsx"?
3. lib/scripts/get_data.sh is not a part of the Simple-bar stack.... so how does this tie in to making the mod work? I don't see anywhere where the script is even called so how is it supposed to work?

Do you actually have this working with the newest simple-bar?

[kvndrsslr]

Hey @hrwtech, sorry I did only update to the latest version just now! I did however do things right this time and created a new Widget for mpc complete with a section in the simple-bar settings to set the host/port of your MPD instance and the format string you like to display. You can try out PR #182 to see it in action.
